WEATHER-STRIPPING- FOR WINDOWS.

Specification of Letters Patent.

Application filed April 18, 1918. Serial No. 229,366.

and such as may be applied to both sashes and thereby afford double protection at the meeting rail and also such as will not in 1. any way prevent easy movement of the sashes during] raising or lowering thereof and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.

' Figure l is :1 general perspective view of a portion of a window showing the upper and lower sashes and my device applied thereto.

Fig. 2 is a plan section taken through Fig. 1 and through the upper sash.

Fig. 3 is a perspective detail of one of my weather strips.

Fig. 4 is an exaggerated sectional plan showing the parting strip and weather strip applied.

In the drawings like letters of reference indicate corresponding parts in the various figures.

1 indicates a window frame, 2 the upper sash, 3 the lower sash and 2* and 3 the meeting rails of the upper and lower sashes. 4 indicates the parting strip, which extends vertically between the guideways 5 and 6 in which the upper and lower sashes move, the upper and lower sashes being provided with the usual notched portions 2 and 3 into which the parting strip extends. 7 indicates a sheet metal strip which is substantially U-shape in cross section, the arms 7 and 7 being spread outwardly toward their ends and curved soas to prevent a convex outer bearing face against which the opposing walls of the notched portions 2 and 3 bear. The strip 7 is formed of spring metal and is sedured to and extends from end to end of the parting strip 4 by nails 8.

It will be noticed on reference to Fig. 4 that the weather strip 7 is secured to the center of the parting strip by nails 7 2 and that such strip is bent outwardly at each side of the nails so that the angle of the strip at each side is free from the corner thereby insuring that the strip at each side of its fastening will have a maximum resiliency.

From this description it will be seen that I have devised a very simple device which will insure of the window being Weatherproof from top to bottom and which is installed by a single application for both sashes at each side of the window, the upper sash bearing against the arm 7 and the lower sash bearing against the arm 7', the strip 7 extending from the bottom ofthe parting strip 4 forms a continuous bearing face for both sashes and, therefore allows of smooth, easy movement, prevents rattling and provides for double protection at the meeting rail of the windows.

WVhat I claim as my invention is:

In a Weatherstrip, the combination with the parting strip 4 of the window, and the upper and lower sashes located on each side thereof and adapted to slide parallel thereto, the sashes each having a longitudinal notch in their adjacent faces, said notches constituting a longitudinal recessed portion when placed in the operative position in the window frame, of greater width and depth than the parting strip 4, and into which the said parting strip extends, of an integrally formed strip of resilient metal 7 secured to the front of the parting strip 4 and having its free sides flared outwardly unconfined from the point of connection with the parting strip 4 to points clear of the corners thereof, said free ends then being bent backwardly to present convex portions against the respective walls of the notches in the sashes.
